I haven't all understand ...
It's not a bug ? Since the 1.8 Minecraft version it doesn't work.
It work as intended ? it's intended to have a bug ? I don't know ...
When it will be resolved?
5 months later in 1.8.1 Minecraft version, the bug still exists ... :/
The bug haven't to be write as "resolved"
I can confirm this being fixed in the latest snapshot as well.
I still encounter the issue on the 1.5.2 pre-release.
I have a Radeon HD 7450 as my graphics card, and this happens to me as well. Optifine seemed to worked until I installed Forge.
Je confirme également les dire des précédentes personnes, de plus personnellement je suis sur un server moddée où j’ai le même problème je vous joins le message d’erreur
